Context: Notes contain concepts and theory, and often, these concepts must be applied in examples (especially in engineering where there are tonnes of examples in the lectures). Examples take up a lot of space in the 'theory' document, and makes scrolling through the document more tedious and makes it harder to find the notes you are looking for in a quick and efficient manner.

Solution: Rather than doing examples in another notebook, it would be nice if you could simply add a page(s) behind or adjacent to the current 'theory' page which you can do examples on. This would make revision more efficient and also lead to more organised notes. This interface should be fairly easy to integrate.
